PERSISTENT HISTORICAL RECORD · NOT A PROPHECY
The most meaningful articles and signs from 2026 forward, organized by the Four Horsemen— plus foundational Owen A. Lamont / Acadian Owenomics pieces that inspired the framing. Curated, linked, and labeled—built so weekly digests can append without reinventing the archive.
I · OVERVALUATION
Are prices unreasonable versus history and sober expert opinion?
Reported IPO ask (~$2T) is not the Series H private mark ($965B). Separating private primary from IPO ask is the overvaluation horseman’s homework.
Trailing fundamentals versus trillion-scale pricing make the overvaluation horseman concrete even before OpenAI trades.
Primary company disclosure pricing an astonishing future into a private mark—overvaluation evidence without claiming the multiple is ‘wrong.’
II · BUBBLE BELIEFS
Does everyone know it’s expensive—and buy because it may get pricier?
Same Owenomics piece dual-tagged under Bubble beliefs: issuance is not just supply—eager buyers who know it is expensive are the greater-fool half of the trade.
Foundational update: Lamont flags epic return dispersion as a bubble-adjacent whirlwind (not itself one of the Four Horsemen). Also covered in Fortune the same week—primary link is Owenomics.
High-credibility dissent enters the mainstream tape—bubble-language and crash framing from a watched skeptic, not anonymous social media.
Primary exchange data: call purchases >52% of retail opening activity in ten mega-cap tech names—buy-anyway behavior you can measure.
Foundational application of the same Four Horsemen to the AI boom: expensive market + bubble beliefs + inflows, but no IPO/issuance wave yet—so boom, not bubble, in Lamont’s read.
Foundational deep-dive on Horseman II: Yale survey evidence that many investors call the market overvalued while still expecting further gains—the greater-fool signature this ledger watches.
Foundational inspiration for this site’s dials: Owen A. Lamont defines the Four Horsemen as overvaluation, bubble beliefs, equity issuance, and investor inflows—the checklist Bubble Burster builds on.
III · ISSUANCE
Are companies and insiders supplying shares into eager demand?
The working ‘final boss’ tripwire slips: filing is not a trading date, and the CEO now explicitly pushes a 2026 listing off the table pending safety work.
A major global exchange listing with a ~$46B top-end valuation and a concrete Sep 17–21 subscription window extends the 2026 issuance procession beyond U.S. AI/space names.
Another outsized 2026 IPO timetable (~$1.6B raise / ~$49B valuation) and explicit retail-democratization framing—issuance appetite outside the AI hectocorns.
Foundational Issuance read: Owenomics on IPOs of doom—how equity supply into eager demand marks a bubble regime. Dual-tagged interest for Bubble beliefs (greater-fool buyers meeting the float).
Dress-rehearsal mega-IPO: enormous primary supply absorbed in a single debut—issuance as market regime, not one-off company story.
Primary paperwork for the thesis tripwire. Filing starts the watchlist clock; it does not start the exit clock until a credible trading date appears.
Precursor event in the AI IPO procession—concrete SEC paperwork ahead of OpenAI’s own filing announcement.
IV · INFLOWS
Are new participants stampeding in—and is leverage expanding?
Seasonal/cycle context already on the home timeline. Useful calendar awareness—not proof that any horseman is riding.
A high-profile AI bull fund exits public equities after a leveraged drawdown—positioning and forced-sale evidence, not a refutation of the tech thesis.
Forced liquidation in a leveraged AI/chip trade is the kind of unwind headline the framework watches—participation funded by margin, not just conviction.
